BATTERY CONNECTION.

Specification of Letters Patent.

Patented Dec; 10, 1907.

application filed April 11-1907. Serial No. 367-652;

.battery connections, particularly to that class of batteries known asdry batteries, and

has for its object the production of a battery connection which doesaway with all connecting wires, screw connections and binding posts onthe battery cell the connecting together of the cells being accomplishedsimply by placing the cells together in a proper box or receptacle. Anda further object of my invention consists in producing with the abovementioned connection the novel means of fastening the above mentionedconnection to the carbon element of the battery. I attain these objectsby means of the device shown in the accompanying drawings Figure 1 is avertical cross-sectional view of my battery through the connection. Fig.

2 is a front view of my battery connection in position. Fig. 3 is a topview of my battery connection in position. Fig. 4 is an enlargedvertical cross-sectional view of a modification of the method offastening my connection to the carbon element, showing additional meansover that shown in Fig. 1. Fig. 5 is a top view of Fig. 4. Fig. 6' showsthree cells having my device grouped so as to operate in parallel. Fig.7 shows three cells with my connection operating in series. Fig. 8 showssix battery cells using my invention grouped so as to'operate in seriesand in parallel at the same time.

In the drawings 2 represents the zinc container which generally formsthe zinc ele-.

ment in dry batteries, and holds the exciting medium 1, the carbonelement 3, and the content retaining, as well as insulating, material 4.The upper end of the carbon element 3 is formed with a ball-shaped headas shown, and the connection 5, which may be a strip of s ring brass,has one end shaped soas to con orm to the said head of carbon clement 3,by cutting out the metal at 8 which with the end is bent forming thelips 11 as shown. To fasten this connection to lips 11 over theball-shaped end of the carbon element, when it will grasp the same,inclosing it tightly, insuring a. good contact which will be protectedand maintained at all times by the insulating compound 4. Connection 5further has a hook 7 cut out of its surface to hold the insulatingmaterial 4 between the metal strip 5 and the zincele-- 'ment 2. The zincelement or container 2 is cut away at 9 to permit connection 5 to .passthrough 'it and be insulated from it.

Fig. 4 shows a modification of the method of fastening my connection tothe carbon element shown in Fig. 1, which consists in the addition oftwisting a wire 10 around the lips 11 so as to rigidly fasten the lips11 against the carbon as shown.

The other end of the connection 5' .is enlarged and bent upward, forminga resilient orspring member 6 which serves as the means for connecting'rny batteries together, as this'is simply pressed or placed againstanother battery'cell and then placing these cells in a proper box orreceptacle, as shown in Figs. 6, 7 and 8, wherein 13 and 12 eachrepresent a strip of metal with binding posts 14 and 15 for connectionwith the external system of wiring.

It is evident with my battery that it is a very simple matter whentesting, to remove a dead cell and replace it wlth another. There are nobinding screws to jar and come loose, no connecting wires to break, allof which, with the ease of replacing a cell even at night time, makes itparticularly adapted for automobile service.

It is evident that I can use any conduct-- connection fastened to thecarbon element and insulated from the zinc element, having its end bentforming a resilient member.

2. In an electrical battery, a metal container, acarbon element with aball-shaped end within said container, a sheetv metal connection,insulated from said container,

having resilient lips embracing the ballshaped end of said carbon, and aresilient member forming a part of said connection the carbon it is onlynecessary to forcethe 1 external to said container.

3. In an electrical battery, a metal 0011- a resilient member on saidconnection eX- tainer, a notch from the side of said conternal to saidcontainer. tainer, a carbon element with a ball-shaped end, a connectionpassing through said notch GEORGE BLOW 5 and insulated from saidcontainer, resilient Witnesses:

lips on said connection for embracing the F. G. MOORE,

ball-shaped end of said carbon element and WILLIAM A. RADTKE.
